CONTINUOUS TONE CODED SQUELCH
SYSTEM (CTCSS)
CTCSS is a feature that allows a group to talk to each
other without hearing other users on the same
channel.
NOTE : Uniden discourages the use of CTCSS feature until the
Australian Communications Authority (ACA) grants the
use of CTCSS on CB frequencies.
Programming CTCSS Code
1. Press [Function] button repeatedly until “[ ]”
appears in the large display.
2. Press [
▲
] or [
▼
] to
select the desired
code.
3. Press [ ] to confirm your selection. Otherwise,
the code selected is automatically accepted if no
key is pressed after 5 Secs.
Setting CTCSS to “OFF” allows the radio to receive all
transmissions on the selected channel regardless of
CTCSS tone.
